1. Actually the tax year is always the current year, as that is when you are sending in your Redemption. Get it online at
www.irs.gov
2. Accept the page that has the itemized summary, or account info, with the letter head of the company and or name, not necessarily the coupon page.
3. Entire set of pages, NOT recommended. Just one page.
4. Copies of an original invoice will have to suffice, as you are doing it multiple times and their is only one original.
5. Remember, this is about YOUR creating your set-off. You could also create your OWN bill if you had all of the elements in the Document.
But stick with the one that you get from the company or agency if able.
